用SAX方式解析XML，XML文件如下：
<?xmlversion="1.0" encoding="gb2312"?>
<person>
<name>王小明</name>
<college>信息学院</college>
<telephone>6258113</telephone>
<notes>男,1955年生,博士，95年调入海南大学</notes>
</person>
事件回调类SAXHandler.java
import java.io.*;
import java.util.Hashtable;
import org.xml.sax.*;
public class SAXHandler extends HandlerBase
{
private Hashtable table = new Hashtable();
private String currentElement = null;
private String currentValue = null;
public void setTable(Hashtable table)
    {
    this.table = table;
    }
public Hashtable getTable()
    {
    return table;
    }
public void startElement(String tag, AttributeList attrs)
throws SAXException
    {
    currentElement = tag;
    }
public void characters(char[] ch, int start, int length)
throws SAXException
    {
    currentValue = new String(ch, start, length);
    }
public void endElement(String name) throws SAXException
    {
    if (currentElement.equals(name))
      table.put(currentElement, currentValue);
    }
}
